US Supreme Court temporarily halts EPA's "good neighbor" rule on downwind pollution enforcement.

The US Supreme Court has temporarily halted the Environmental Protection Agency's (EPA) "good neighbor" rule, which aimed to limit downwind pollution from power plants in nearly a dozen states. This decision comes as legal challenges against the rule continue in separate jurisdictions. The "good neighbor" rule aims to limit air pollution and its impact on regional air quality. The Supreme Court's action temporarily prevents the EPA from enforcing the regulation until the legal challenges are resolved.
